UNITED STATES PATENT WILLIAM K. HOBAOK, O F BENTONVILLE, ARKANSAS.

Specification forming part of Letters Patent NO. 197,134, dated November13, 1877; application filed March 30, 1877. I

of Bentonville, in the county of Benton and State of Arkansas, haveinvented a new and Improved Oooperin g Apparatus and I do hereby declarethat the following is a full, clear, and

exact description of the same.

The invention relates to an improved apparatus for use in applying thehoops of barrels, hogsheads, or other casks whose staves are straightand not jointed.

The invention consists in the construction, arrangement, and combinationof parts, as hereinafter described and claimed.

In the accompanying drawing, Figures 1 and 2 are, respectively, a sideand sectional elevation of the apparatus, with a portion of the stavesrequired to form a barrel or hogshead set up and secured to one of thecircular heads. Fig. 3 is another side elevation, and Fig. 4: ahorizontal section.

-The several movable or working parts of the apparatus are variouslyattached to and arranged in a rectangular frame, A. From the center ofupper part of said frame are pendent four slotted bars, a a, serving asa support and guide for the circular plate B, which has a concentricgroove, 0, to receive the upper ends of the staves d, and therebyconstitute the upper former. A Windlass, e, and pulleys f are suitablyarranged on and attached to the upper side of plate B, for use inraising and lowering the iron band or hoop D by means of thesuspendingropes g. Said hoop is divided transversely, and its bent orflanged ends connected by a screw, h, so that the hoop may be enlargedor contracted in diameter as required to adapt it to alternately clampand release the staves.

E indicates a circular anvil or former, having an iron rim. It is fixedon the lower end of a grooved stem, F, which works through acorrespondingly-shaped aperture in the grooved plate B, and serves toguide the anvil while being raised or lowered by the rope G and WindlassH.

A circular former, I, is fixed to the bed of frame A, and arrangeddirectly under the upper former or plate B.

The clamp K is used for holding the end of a hoop and drawing it tightlyaround the staves when placed together in proper posi' tionnamely, in acircle. The clamp is constructed upon the principle of ice-tongs, and aWindlass-rope, L, is attached to it.

The Windlass M is mounted in a frame, N, which slides vertically ingrooved guides formed by studs j of frame A. The studs are provided withnotches l, to receive the claws or flanges formed on the upper ends ofsprings 0 attached to frame N.

Normally, the springs retain such a position that their claws enter thenotches l, and thus hold the frame N fixed in any position to which itmay be adjusted. To push out the springs,

and thus disengage the claws from the notches l, and allow theWindlass-frame N to be adjusted higher or lower, I employ pivoted leversm, which may be arranged like the parts of a compound lever, so that byoperating one the other will be operated also.

The mode of using the apparatus in setting up and hooping a barrel,hogshead, or other cask, is as follows: The lower head 10 of the cask isfirst laid upon the lower circular former I, and the upper former B islowered into the required position, which will always correspond to thelength of the staves of the cask. The first stave is set verticallyopposite the crankscrew It, with its lower end against the former I andits upper end in the circular groove of former B. The screw B is thenturned to clamp the stave in such position, and the latter thereafterserves as a guide by which to set the other staves. As each stave issuccessively put in place, it may be lightly nailed to the lower formerI, as shown in Fig. 1, and its upper end secured by iron pins insertedin holes 0 in the upper former B. In order to crowd the staves as closetogether as possible, a lever (not shown) of suitable construction isused, its pointed end being inserted in fulcrinnholes in the lowerformer I.

To apply the first hoop s it is nailed at one end to the lower former I,and then drawn taut around the cask by means of the clamp K and WindlassM. The circular anvil E is then lowered opposite, by Windlass-rope G,into a position opposite the place where the second hoop is to beapplied, and the hoop or iron band D is next lowered to a point justabovethe anvil, and the screw is turned to cause it to clamp the stavestightly against the anvil. The wooden Y hoop is then nailed andstretched around the cask, as in the first case, the anvil, in suchcase, supporting the staves and turning and clinching the points of thenails as they are driven through the staves. The anvil and band D areraised before each succeeding hoop is applied, and the windlassfi'ame Mis also raised correspondingly, in order that the clamp may draw thehoop horizontally, or in a line at right angles to the side of the cask.

The last two hoops may be applied after the former B and band D havebeen raised clear of the cask. The upper head is then inserted andsecurely nailed, when, the crank-screw R being loosened, the cask may beremoved from the platform.

! j, Windlass M, and clamp, as and for the purpose specified.
